google.. login
Didn't provide any information of value, then charged my account.
I canceled my trial, and was still charged for a yearly premium subscription. would not recommend.
it doesn't work when the fan or ac is on, in middle east and asia we have long summer hence ac and fans at night are common so it should work accordingly. i want refund
no way to turn off the notification ads for premium. i did not sign up for my alarm clock to buzz me with ads. this app was so handy. too bad though, uninstalled. not coming back.
do I look like I want to watch an unskippable intro? NO!
- i find i sleep better without it. - it misjudges time taken to fall asleep at least twice per week. if it gets that wrong, what reason is there to be confident that it really knows when youre in deep sleep? i asked for a refund but did not get one.
all features became paid !
I use it mainly for the smart alarm, while the sleep tracker is neat and all but I don't really care about that. What made me decide to give this a one stat is because they decided it was smart to make a core feature locked behind paywall.
R419 ??? really?? keep it!
uninstalled because the main selling point of the app is a premium feature now terrible decision
made smart alarm paid only when it was free for like 10 years
I was using this as an alarm for years and the smart alarm was a nice feature. The only free thing it gave you. Suddenly tonight I went to set the smart alarm like I do every night and discovered they now made it a paid feature... Disappointing. They need to fix their sales model. They don't even offer a free trial. Maybe if I actually tried out the paid features first I would have started paying. They only have an annual billing option too.
the only feature that made the app worth using in the first place is now paid. uninstalled
...and under the guise of "bug fixes and updates" the wake-up-easy function is not available to free accounts anymore. Enshittification successful, app uninstalled.
Turned the smart alarm into a premium feature after years of offering it for free. Uninstalled.
little bit confusing....
they've just paywalled the smart wake up feature which was the whole point of the app.
Rubbish
You've made smart alarm paid! Greedy bastards!
latest update 17/03/2026 now this smart alarm is only for premium user. might as well uninstall and just use normal alarm getting more inaccurate after so much updates. Alarm once I turn off, it still sounds until I go back to the main page where you can set the alarm
They just subscription pay-walled the Smart Alarm, one of the primary and most popular functions of the app, which costs them nothing. Thankfully "Sleep as Android: Smart Alarm" also has this feature so I've switched and not looking back. Beware of these developers, they'll remove features in attempt for more profit.
I have used this app for over 10 years. The most recent update is the final straw. After a decade, you lock the smart alarm behind the premium subscription??? It's the literal first and only feature I started using this app for because it's the ALARM that TRACKS your SLEEP CYCLE. What a shame to see an app reduced to pure garbage!
referal program that was promised upon purchase is nowhere to be found + the app only allows for 1y payments
It was an amazing app, I have the premium plan however on my new phone Galaxy S26 Ultra it has a huge bug, doesnt work. Hope soon this bug can be fixed.
I don't want to pay year and I think it's a bit ridiculous.I don't have the option to pay monthly.
Totally ineffective. 1) recorded me as sleeping when I was cleaning the fridge and taking my tesco delivery in while chatting with my parents. 2) phone then decided to delete that and record sleep, but inverted the times: woke up at 6, that was when it recorded my deepest sleep. 3) App refuses to download to watch, no issue with any others.
Recent update has made this app unusable. It freezes when opened and is non-functional. Been using it for years and now it's defunct.
I've been using this app since like 2023 or something... And as of right now? I got Revolut Premium to buy it for me, but I'm like... I'm having nightmares, from just the song alone. I'm trying to wake up, but I was like: "I KNOW YOU CAN HEAR ME. PLEASE JUST LISTEN, AND STOP WAKING ME UP AT THESE TIMES! PLEASE!" but of course it was a dream, so it wasn't audible.
zero functionality without subscription
They will not cancel my membership and refund my $50 I am not satisfied with this app
it's not that informative
Doesn't answer emails I cancelled my subscription within the 14 days and I reached out several times via email and have not received a response. App was ok but was limited when sharing a room.
It does not count sleep at all
I followed there rules for cancelation and refunds however I've been ignored and not given my refund 10 out of 10 would not recommend
Doesn't use any biometric data from your watch. 😂 Just "listens" using your phone's mic? Hehe. What an absolute complete waste of everyone's time. UNINSTALLED
Very inaccurate. Says I haven't slept when I've been out for hours. Definitely not worth the sub I got a couple of days ago.
tl;dr you are paying for randomly generated plots This app CANNOT reliably detect whether or not I'm asleep. Twice already I woke up in the middle of the night and used the phone to play an audiobook. Both times the app registered it as sleep talking. Regardless, NEVER buy a 1 year subscription to anything! I can't believe I made this mistake.
Actually impossible to cancel this God damn subscription. Can't do it in play store (simply doesn't appear). Can't do it on the website because it says to go to play store. Great feedback loop of insanity.
all fun features require $33 annually. absurd.
Completely disappointed after purchasing this app. It shows me constantly sleeping throughout the night, even though I know I was awake to use the bathroom and let the dog out. my watch tracks me being awake during those periods, but this app shows no movement or noise. Yes I have the permission on for microphone and have turned on the sensors in the watch app. So disappointed with this purchase.
I've been using this app for years without issue. Almost a decade. However, I just received a notification to prompt me to get the premium version. I've been using this app all this time because it hasn't pestered me to do so.
They are slowly removing features and putting them behind a pay wall. I used to pay for this app, but had to temporarily cancel my subscription until i can afford to budget it. They removed the ability to have a "wake-up window" in the free version, so I guess I will be deleting the whole thing and not paying again in the future. I have recommended it to many people and it is disappointing to see them cutting corners wherever they have to squeeze people into paying. Otherwise it works fine.
I don't like keeping my phone next to me so I charge it across the room (so I stay off of it). It says this is available for a Tablet, however, when I try to download it on my tablet, I can't find it in Google Play. I already signed up for the free trial so I'm going to try it on my phone for at least tonight, but I REALLY want to use it on my Tablet. If I can't, I won't be purchasing.
I was not given a chance or warning before the year subscription kicked in. I wanted to test the app for longer than a month, especially over daylight savings, before I purchased. Today I, with no warning, had a charge for the next year.
They store all your health data encrypted (they can read it at any time) on their servers, and they may use it for legal requests (e.g. from police or government). They store your health data up to one year after you delete the app. You CAN'T simply request to delete your data, you need to be eligible to do it. Considering it's made in Sweden, this app is a privacy nightmare. Wake up.
I don't believe is it accurately tracking what is happening. I was up from 4am, on my phone, and it has me as deep sleep throughout.
